The Governor's Citadel and Palace in Bastia dates back to the 14th century. The former palace of the Genoese governors houses the municipal museum, formerly the Ethnology Museum of Corsica.Abutting the old fortress tower and decorated with a 14th-century campanile, the Palace of Governors over the centuries guarded Terra Nova and beyond the ramparts of the Old Port. The city has undertaken a program of renovation of the palace under the direction of architects Cléris Daniel and Jean-Michel Daubourg.
Besides the renovation of the palace the work helped to rebuild the part of the monument that was destroyed in 1943 during the fighting for the liberation of Corsica. The new museum was inaugurated in June 2010. The museum collections are organized into four themes: birth and urban growth, centre of power, cultural centre, and the Palace of Governors. The turret of the submarine Casabianca was preserved in the courtyard until the renovations.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
